The curvature of the endotracheal tube conforms to the shape of the airway with the head held in the neutral position, and is easier to insert then if the tube was straight. This development, largely, is an accident.
1. Methyl anthranilate, also known as MA, methyl 2-aminobenzoate, or carbomethoxyaniline, is an ester of anthranilic acid. The chemical formula for this compound is C8H9NO2. Methyl anthranilate is a clear to pale yellow liquid with a melting point of 24Â°C and a boiling point of 256Â°.n ester is the product of a reaction between an alcohol and an acid, usually an organic acid.3 Methyl anthranilate is derived from the reaction of methanol and anthranilic acid.
Anthrax (http://edis.ifas.ufl.edu/MB001)âAnthrax is mainly a disease of herbivorous animals such as sheep, horses, and cattle. In humans, the disease usually ocurrs only in people who work with these animals or their products. The causative agent, the bacterium Bacillus anthracis, can cause three different kinds of disease: cutaneous anthrax, intestinal anthrax, and pulmonary anthrax. All three types can be fatal. Cutaneous anthrax is characterized by skin ulcerations with black necrotic areas and swelling of the lymph glands. Inhalation anthrax causes severe breathing problems and shock and is usually fatal. Intestinal anthrax causes nausea, vomiting and fever, followed by vomiting blood and severe diarrhea. Antimicrobial and insecticide resistanceâWidespread use of antimicrobials has spurred evolutionary adaptations that enable bacteria and other microbes such as viruses, fungi, and parasites to survive these powerful drugs.
